一、概述 干法缠绕具有许多优点,如制品的树脂含量不受缠绕张力和缠绕制品直径大小的影响;产品质量易于控制;树脂的选择范围较宽;纱片不易打滑,适于绕制形状较为复杂的制品;可以进行快速缠绕以及工作环境清洁、气味小等。因此,这种工艺在国内外受到了很大重视,尤其在制造诸如火箭发动机壳体等精度要求高的制品,得到了广泛的应用。 First, an overview Dry-winding has many advantages, such as the resin content of the product from the winding tension and winding the diameter of the product size; easy to control the quality of the product; wide selection of resins; yarn is not easy to slip, suitable for winding shape is more Complex products; can be quickly wound and the working environment clean, odorless and so on. Therefore, this kind of technology has received great attention both at home and abroad, and has been widely used especially in the manufacture of high precision products such as rocket engine housings.
